Air Force theory: Missing pilot intentionally flew off course

WASHINGTON (CNN) -- Air Force investigators are now operating
under the theory that a missing fighter pilot deliberately
flew his plane off course, senior Air Force officials told
CNN.

Capt. Craig Button, 32, disappeared April 2 about 90 minutes
after takeoff while flying in a three-plane formation across
southern Arizona. Button and his A-10 Thunderbolt were last spotted on radar near Colorado's
New York Mountain, about 100 miles west of Denver.
